Air cleaner restriction of 20hp. What are you running?


Recommended Posts

I recently dyno'd the Mach and found that my 13" K&N Air Filter with the cast Ford Racing Air cleaner base and lid, resulted in a 20hp loss. Ran it with the air cleaner and without and it picked up 20hp without the filter.

I have been searching for a 13" air filter ever since and the closest thing that would fit is a skinny little 12" K&N Filter from Summit.

I was shocked to find out that there was such a huge hp loss with the filter on, especially being a K&N, but apparently the air cleaner top so close to the air horn is causing a big restriction. I put a 2" spacer on it, which helped a little, but I can still tell the power difference at WOT with and without the filter on. So my search goes on.

Currently not running the ram air, but considering going that route.

I am running an open element filter lid. Its K&N style fabric. But the lid essentially becomes a filter also letting more air in.

If you have the space under the hood, just get a taller filter element, same diameter, and a longer stud for the lid.
